Delicious is from a different era. I don't know if you all remember, but it was launched and influential when "social" powered sites (see Digg) were all the rage.<p>The most powerful feature of Delicious for me was the /popular/ page, which showed me at a quick glance what sites/pages were trending for that day. Usually it reflected what was on the home page of Digg, and a few other influential tech sites.<p>Moving forward, the idea of user generated content & socially powered websites lost some steam (although the concept is still around) and Delicious lost it's chance to make the site into a profitable force online.
